The aim here was to maximise psi performance in the ganzfeld in the process of testing the claims for identical twins as a source of psi-gifted individuals. The report here concerns the results of the testing of ten of the planned fifteen pairs of identical twins who were selected on the basis of a form of the Sheep-Goat questionnaire and then their ESP performance evaluated with two sessions of the Real Time Digital Ganzfeld. They obtained a 40% hit rate and a medium effect size.
